GEORGE W. WELGH, OF MARSH-ALL, MICHIGAN, ASSIGNOR TO BROOKS RUPT'URE AP- PLIANCE COMPANY, OF lvLARSHALL, MICHIGAN, A, COPARTNERSHIP COMPOSED OF ELLEN J. BROOKS, LOUIS E. BROOKS, AND HAROLD C. BROOKS.

TRUSS.

Application filed April 24, 1925. Serial No. 25,515.

This invention relates to improvements in trusses.

The object of the invention is to provide improved pad casing and means of retalning and supporting the belt and cross strap.

Objects pertaining to details of construction and operation will appear from the detailed description to follow.

I accomplish the objects of the invention by the devices and means described in the following specification. The invention is defined in the claims.

A structure which is a preferred embodiment of the invention is illustrated in the accompanying drawing, forming a part of this application, in which Fig. I' is a plan view of a truss pad and fragments of the belt and cross strap, from the pad side.

Fig. II is a similar view from the back or case side.

Fig. III is a detail sectional elevation view taken on line 83 of FigsI, II and IV.

Fig. IV is a detail cross sectional View taken on line 4.4 of Figs. I, II and III.

Figs. V and VI are front and back views of the structure as applied to an oval pad truss.

In the drawing similar numerals of reference refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows at the ends of the'section lines.

The parts ofthe drawing will be identifled by their numbers. 1 is the belt, 2 is the cross strap, 3 is the back frame or support for the cushion pad having a strap recess 1 for the belt and across aperture 5 for securing the cross strap end. 6 is the hollow rubber cushion pad, hemispherical in form and of comparatively soft vulcanized rubber. Across the hardrubber casing or back 3 is the belt recess 4 with a cross bar 41 embracing the belt 1. The belt is of elastic material and normally slightly wider than this recess, so that it effectively engages the case 3 and supports it in position by friction of the sides.

Preferably a peripheral flange 31 is on the front face of the casing extended into an inwardly-projecting annular bead 32, forming an annular recess 33, as seen particularly in- Figs. III and IV. The rubber pad 6 is hemispherical and hollow and at its periphery is recessed by external groove at 61 with an outwardly-projecting peripheral bead 62 conformed to the bead 32 and recess 33 of the case. The pad may be otherwise secured. My invention does not pertain to the method of securing the pad.

The cross strap 2 is inserted through the transverse aperture 5 in the case (see Figs. II and IV). The inner end of the cross strap 2 is folded on itself at 21 and retained by a seam of stitches 22. This enlarges the inner end of the cross strap so that it seats within the aperture within the body of the case 1, and contacts with the side of the elastic belt 4, effectively retaining the cross strap in place and providing an effective friction means at the edge of the belt. At the same time these parts are very readily removable and adjustable without other clamping and attaching means.

I have not shown the buckles for these, straps, as my invention in no way pertains to them. In Figs. VI and VII I show an oval pad with a back 3 and rubber cushion 6'. The back bar 41' is on the diagonal to receive the belt 1, andthe cross strap 2 is retgiined in the same way as on a circular pa I therefore desire to claim the invention 7 ture, and a cross strap disposed within the transverse aperture with its inner end folded upon itself and stitched to form an engaging portion for the inner end and to afford friction means for the side of the belt, as specified.

2. A truss structure consisting of a suitable soft cushion pad, a casing or body therefor with a belt aperture recess through the back thereof, a transverse aperture for a cross strap extending'into said belt aperture,

' other, as specified. 10

In Witness whereof, I have hereunto set my hand.

GEORGE W. WELGI-I.
